Java - Android - Split Activity/Class into multiple files for better organization (solution)

由 [亡魂溺海] 提交于 2019-11-27 16:22:37
问题 I'm not PRO in JAVA , but I found myself of getting crazy with Android activities getting too large. After a few pages of code length I found myself of permanently scrolling back and forth! Not only OnClickhandlers can grow huge, just a lot of code tends to sum up in a bigger activity. Fragments were no solution for me. In general Java does not allow to split up a class into several files so a hack is needed. I browsed through a lot of stackoverflow threads regarding that, not one had a

grails / external configuration / grails.config.locations - absolute path file “Does not exist”?

由 我只是一个虾纸丫 提交于 2019-11-27 13:32:14
问题 I'm trying to use Grails' built-in mechanism for loading external configuration files (*.groovy and *.properties) outside the deployed WAR file. The documentation implies this is just a case of setting grails.config.locations with the appropriate classpath: or file: paths. I've configured Config.groovy with: String externalConfigLocation = System.getProperty("SYSTEM_PROPERTY_KEY") if (!grails.config.locations || !(grails.config.locations instanceof List)) { grails.config.locations = [] } if

E.g. you have www

Piping buffer to external command in Vim

由 心不动则不痛 提交于 2019-11-27 10:35:46
I am kind of a Vim novice. I would like to send contents of the current buffer to stdin of external command (lets say mail). My final purpose is to set a shortcut to quickly send email from current Vim buffer. I am guessing this should be a trivial stuff, but I couldn't find a way to send Vim buffer to an external command. Thanks in advance. You can use :w !cmd to write the current buffer to the stdin of an external command. From :help :w_c : :[range]w[rite] [++opt] !{cmd} Execute {cmd} with [range] lines as standard input (note the space in front of the '!' ). {cmd} is executed like with ":!

Loading external script with jinja2 template directive

由 此生再无相见时 提交于 2019-11-27 10:22:20
问题 I'm very new to jinja2 and the use of templates in general so I was wondering if there's an easy way to load an external javascript. I was thinking of using: {% block javascript %} <script src="myscript.js"></script> {% endblock %} But I can't help to ask: Is there a way of loading this script directly from within a template directive? 回答1: You have two choices here -- the first is the way you did it -- simply add the appropriate markup into a template (or a block if you want to be able to

How do you cancel an external git diff?

由 十年热恋 提交于 2019-11-27 07:52:41
I've got vim setup as my external diff tool: [diff] external = git_diff_wrapper #!/bin/sh vimdiff "$2" "$5" Say I have 300 files that have been modified; via bash, I type "git diff". It launches 300 vimdiffs sequentially, how do I abort it? If stopping the process is not enough, killing the shell itself (in which you launched the git diff ) might be more effective. See also Git Diff with Vimdiff Not being ready to go full speed into using vimdiff (I’m just new to it), I put the following in ‘ gitvimdiff ’. The result is that I can use vimdiff to look at git-diff by running ‘ gitvimdiff ‘, but
